Navigation: Ideas for Investigation We’ve been trying to figure out where food molecules come from in plants. We think plants must be making them from parts that they take in. One tool we can use is a simulation to figure out how all the parts of the system are interacting.

If we could represent what is going on inside a plant using a simulation:

What inputs and outputs of the plant system would we want to represent?

What structures of the plant would we want to represent?

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.

The energy of a photon is equal to (what) times (what) of the photon.
